TE712B: The classic model used by the German Army and a French service,
It offers memory storage, remote control, antennas selection, line output attenuator, 30Khz and 13Khz IF outputs,< BR>
Drawers are horizontally arranged with a centered power supply bloc.

TE712B: Another model that may have been in use in a German weather service(many thanks to Joachim),
It has an overload indicator but no memory storage, nor 13Khz IF output,
Drawers are vertically arranged with a left side power supply bloc.
This could be a prototype or a pre-production model.
I am looking for manual, schematics and any information on that TE712B model

TE712S: A reduced functionnality classic TE712B
It has only six filters, no remote control, no F1/F4 mode, no notch filter, no spur filters, no AFC and no diversity mode.
